Thanks, looks like you hit the nail on the head.

Playing around with the command line I was able to get connected using -c
des. Here is what is in /etc/ssh/ssh_config

#   Cipher 3des
#   Ciphers
aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc

I see that they are commented out. Normally this documents the hard coded
defaults: 

Looks like I need to change thsi to look like:

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc,des

right?
